Quote from taowave:
On volume based bars,does each stock have its own "volume filter",or is it based on some % of an average??
It simply builds a bar for whatever specified amount you tell the software. So instead of having a bar that forms every 3 min, you could change it and have it build a bar every 5000 shares. Of course, different markets are going to require different settings. I trade futures so my settings are going to be totally different then someone who trades stocks.
There is no magical number that will produce the best results, you just have to find a setting that appeals to you.
There is a formula on Tradestation's forum, that will give you an approximation of what what the volume bars equal in time. ( example, 1200 volume bars would equal about a 3 min chart.) Ill look later to see if I can find it.
